The trial is postponed pending the completion of other ongoing pre-clinical and clinical work.

The main purpose of this research study is to evaluate the effect of multiple doses of an investigational drug known as JNJ-31001074 on the single dose of combination oral contraceptive Ovral-L containing ethinyl estradiol and levonorgestrel in healthy women who cannot bear children. This study will look at the safety, tolerability (how the drug makes you feel) and pharmacokinetics (what your body does to the drug) of either drug alone and in combination in healthy women.

This is an open-label (both the physician and patient know which treatment will be administered), single center randomized, drug-drug interaction study in healthy female volunteers of non-child bearing potential. A total of 32 volunteers will be enrolled. The study consists of a screening phase, an open label treatment period, and end of study/early withdrawal assessments. Volunteers will be randomly assigned to 1 of 2 treatment sequences. The open-label treatment phase will consist of two periods. In each period, volunteers will receive either of the following treatment(s): Treatment A: a single dose of oral contraceptive containing 0.03 mg ethinyl estradiol and 0.15 mg levonorgestrel (Ovral-L) on Day 1 and Treatment B: multiple daily doses of 10 mg JNJ-31001074 on Days 1 to 8 and a single dose of oral contraceptive containing 0.03 mg ethinyl estradiol and 0.15 mg levonorgestrel (Ovral-L) on Day 7. A washout (no treatment break or drug holiday) period of 28 days separates the two occasions of single dose administration of oral contraceptives in Periods 1 and 2. Safety and tolerability will be assessed from the time of informed consent to the end-of-study evaluations or early withdrawal. Volunteers will be instructed to report any serious adverse events that occur up to 30 days following the last dose of study drugs. For Treatment A, the volunteer will receive a single dose of oral contraceptive. For Treatment B, the volunteer will receive 10 mg tablet of JNJ-31001074 once daily orally for eight days (Days 1 to 8) and a single dose of oral contraceptive on Day 7.
